Maria Roswitha Anal Work Official

Wait, perhaps the user is referring to the "Anal Work" as in the anatomical drawings or something related to her works? Let me think. Another angle: Hildegard von Bingen did write about medicine and natural science, which included some anatomical descriptions. Could this be related? Maybe the user is referring to her work in natural science or medicine? But "Anal Work" as a title or a specific type of work isn't one I recognize.
